T o all whom tf/nay concer/n.'

Be. it vknown that I, JOSEPH RosnNBLAT'r, a citizen of the United States, and resident of the city of Providence, in the county of Providence and Statevof Rhode Island, have invented certain new and useful Improve-v ments in Eyeglass-ldountings, of which the Y following is a specification.

This invention relates to mountings for eyeglasses,l spectacles yand the like and relates more particularly to Vmeans for securely fas tening the lens in the. mounting.

The, primary` object of my invention is the provision of means whereby `when the screw is brought to its seat the same is securelylocked in that position against being accidentally withdrawn.

A further object ofthe invention is the provision of means whereby the act of finally positioning the binding member such as a screw or rivet through the ear and lens serves to seat the lens tightly against the saddle portion of the clip.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. Y

In the accompanying drawings:

Figure 1- is a side elevation showing a portion of the lens held in its clip and a screw having an eccentric head adapted to engage a correspondingly shaped opening in the clamp earwhereby when rotated to position it draws the saddle firmly against the edge of the lens, this head being also shown as provided with my improved locking means.

Fig. 2-is-a section of the lens clip showing the particular form of screw illustrated in Fig. 1 in position in this clip.

Fig. 3- is a side elevation showing a raised cam-shaped member on the lens strap or ear engaged Vby a protuberance on the side of the screw head for the purpose of drawing the clipagainst the edge of the lens and simultaneously locking the screw in seated position.

Fig. 4- is a sectional edge view of the structure illustratedin Fig. 3.

It should be clearly understood that in this invention the essential feature is the provision of a lock in the screw which does not depend on the drawing of the two lens clamp ears toward each other, but rather one '.EYEGril-'.1ASiS-IVIOlllllll'JNGr.V

l Specification of Letters Patent. Y Pigmente@ NOV, 25,1919, Y Application filed December 15, 1916. Serial No. 137,097. i d Y i 3 thatk acts in line with thehorizontal aXis of the lens, which construction needs no particularV 4space to be left between the ears and lens,v to permit my lock to operate as in rotating'my screwv to its seat the lens is dra'wn'toward its saddle.. Y

In carrying out .my invention, 10 desig nates the nose bridge member which joins rthe'twoy lens straps or clips 11. Each clip isprovided with'a saddle portion 12 and in some cases a pair of side or clamping ears 4l between winch the lens 141s held.v In other instances but one of. these ears 41 is employed, the opposite ear being removed" as illustrated in Fig. 2 for purposes hereinafter described while in other cases two ears are employed as illustrated in Fig. 4.

One of the features of my lens clip is the means whereby I forcethe edge 15 of the lens against the saddle portion 12 by the positioning of the screw 32 through the ear and lens.

One simple means for accomplishing this longitudinalrelative movement of the lensl and clip is illustrated in Figs. .1 and 2 which the head portion 31 of the screw 32 1s formed eccentric to the aXis of the screw, whereby when the screw is forced home this eccentric engages a correspondingly eccentric opening 38 in the strap and forces the edge of the lens to a seat 15 in the saddle 34.

The edge of this screw is shown as being attened as at 35 for the purpose of engaging a correspondingly flat face 36 of the raised portion 37 on theear- 38.

Another means of providing a relative endwise movement of the lens and clip is'to provide an abutment 39 on the lug 40 of the ear 41, see Fig. 3, which abutment is engaged by a protuberance 42 on the edge of the screw head 43, which structure performs two functions: first, to produce a relative endwise movement of the lens and clip and also to cause ythis protuberance to engage a recess 44 in the raised portion 40 for the purpose of providing a lock to prevent a rotation of the screw after having been forced to its seat.

A clip having but one ear as illustrated in Fig. 2 is also well adapted to receive lenses of different thicknesses.

I have illustrated a number of means whereby my invention may be carried out, but I do not wish to limit myself to any of these specic constructions as various changes in shape and form-fofrtheseveral features may be necessary. Iftherefore desire it to be understood that vI reserve the privilege'of resorting to all` the mechanical i changes to which the device is clearly Y, *y susceptible, the invention being defined by the terms 0I" the appended claims.

Iclaim. Y 1. A' lens clip comprising an ear provided withv a counterbore having a protuberance at, Vits periphery substantially in line with the v tuberanceon the ear whereby a tension is exerted between the ear and screw as` the latter is turned to its seatto prevent the screw from loosening.

2. A lens clip comprising an ear lprovided :with a eonnterborel having a liattened portion extending within the circleV of said bore substantially in v'line with the horizontal axis' of the lens, ya binding screw passingV tion being 'substantially in line with the `through said ear and lens, headgofsaid `25 screw beingcut awayY andv correspondingly atte'ned von its l'periphery' to engage said flattened portion on the ear,whereby a tension is exerted between the ear and screw lin turning the latter to itsy loosening of the'screw.
